ABSTRACTObjective. This study determined the main dietary sources of urinary molybdenum (Mo) concentrations in a sample of 124 pregnant women in Mexico. Materials and methods. Dietary data was collected during pregnancy, through a semiqualitative food frequency questionnaire, with information of 84 foods. Urine Mo levels were determined by atomic absorption spectrometry, for at least two trimesters of pregnancy. The associations with Mo levels were estimated by generalized mixed effect regression models. Results. Between 5.8 to 12.7% of the samples were above the 95th percentile of urinary Mo distribution reported by National Health and Nutrition Examination Survey (NHANES) 2009-2010 for women (151 µg/L and 148 µg/g creatinine). After bootstrap resampling was conducted, women with high-consumption of hot peppers (β=1.34µg/g; 95% CI: 1.00-1.80; p= 0.05) had marginally higher urinary Mo concentration levels, creatinine adjusted, compared to women with low-consumption. Conclusion. Hot chili pepper consumption may contribute to body burden Mo levels in this population.
